title: [The level of carbohydrate-deficient transferrin is highly increased in bodybuilders].
abstract: Up to now, the measurement of carbohydrate-deficient transferrin (CDT) has been used in persons with a regular alcohol consumption of >60 g/day; primarily due to aspects of insurance medicine, as its levels have an informative value even at 2 to 3 weeks after the discontinuation of consumption.
  
  
  OBJECTIVE
  In the literature concerning % CDT levels in individuals who used chemicals, medical drugs, food supplements and muscle-tissue increasing drugs there is scarce information, therefore these cases in this paper deserve interest.
  
  
  METHODS
  The authors demonstrate the history and laboratory results of three cases. All of them were ethanol abstinent and they had used protein-containing food supplements for one or two months. The measurement of the % CDT showed elevated values.
  
  
  CONCLUSIONS
  All the three bodybuilder individuals are healthy, alcohol abstinent. They had consumed muscle-tissue increasing food supplement for one or two months. The authors consider these high CDT values as consequences of an injury caused by exposition to the protein increasing food supplements.
